TitleDoes FEC only work on SR4 modules on VDX 6940 ?
Question
Does FEC (Forward error correction) only work on SR4 Modules in the VDX 6940 ?
As shown in the RAS Log message BL-1053
FEC is disabled for 100G Interface 104. Media is non-SR4.


 
Environment
  • VDX 6940
  • 100 Gbe QSFP28
Answer
According to the VDX 6940 Hardware installation guide only SR4 optics are referred to.
 
100 GbE QSFP28 SR4 optics support Forward error correction (FEC). FEC enhances data reliability by inserting redundant
data, called error correcting code, into data being transmitted or stored. FEC is enabled by default on the Extreme QSFP28
SR4 optics.
